Angelilli v. Activision Blizzard: Video Game Addiction Complaint

By David Meldofsky, California-licensed attorney · Founder, Lawsuit Informer

Last updated: June 25, 2026

This page hosts a primary court document: the complaint in Angelilli v. Activision Blizzard, Inc., one of the five Schedule A actions in the MDL No. 3109 petition. Below is a plain-English summary, the causes of action, the key allegations transcribed, and the original PDF. It is part of our coverage of Video Game Addiction Lawsuits.

Case status:

Filed December 6, 2023 in the U.S. District Court for the Northern District of Illinois (No. 1:23-cv-16566). Angelilli was one of the five Schedule A actions in the petition to create a nationwide MDL; the JPML denied centralization in June 2024 (MDL No. 3109), so the case proceeds individually.

About this document:

This page reproduces and summarizes a civil complaint. A complaint is the filing that begins a lawsuit, and every statement in it is an unproven allegation made by the plaintiff. The defendants deny these allegations or have not yet responded in court, and nothing on this page is a finding that any company named did anything wrong. A complaint reflects only one side's account.

Plain-English Summary

This complaint was brought by Jaclyn Angelilli on behalf of her child, D.G., against Activision Blizzard and a large group of other game companies and platforms. It alleges that the companies designed their games to be addictive to minors and failed to warn families, and it pleads a civil conspiracy among the companies to "addict a generation of young video game players."

According to the order from the Judicial Panel on Multidistrict Litigation, the games at issue in Angelilli include Call of Duty, Fortnite, Roblox, and Grand Theft Auto. The complaint alleges that D.G. began gaming at a young age and developed a compulsive pattern of use, and that D.G. was diagnosed with depression, ADHD, and oppositional defiant disorder and requires counseling and educational support.

At 210 pages and nineteen counts, Angelilli is one of the most detailed complaints in this group, and it was one of the five lead actions in the petition to consolidate the cases nationwide. For the order denying that petition, see our page on the MDL No. 3109 order.

Causes of Action

The complaint sets out the following claims. Each is an allegation the plaintiff would have to prove; listing them does not mean any has been established.

Key Allegations (Transcribed)

The text below is transcribed and condensed from the filing so the primary source is readable and searchable. The full 210-page complaint, including every numbered paragraph and all nineteen counts, is embedded below.

Transcribed from the complaint's Nature of the Action. These are the plaintiff's allegations.

The complaint alleges that "video game addiction, also called internet gaming disorder, is a condition characterized by severely reduced control over gaming habits and increasing priority given to gaming over other activities, resulting in negative consequences in many aspects of a person's life, including self-care, relationships, school, and work."

It alleges that the defendants "manufactured, published, marketed, and sold video games, gaming platforms, and/or gaming hardware" that they "had specifically developed and designed to cause the addiction experienced" by the plaintiff and other users, using "traditional game tactics such as feedback loops and reward systems, along with patented designs containing addictive features and technology to ensure its users keep playing longer and spending more on 'microtransactions' within the game."

The complaint further alleges that the defendants "design their games to keep consumers playing — and spending — by enlisting the help of behavioral psychologists and neuroscientists" and that, "by acquiring — and addicting — users when they are young," the defendants secure "their profit stream by ensuring future engagement and monetization as these young users age." It characterizes this as the use of "unfair, unconscionable, and deceptive trade practices and conduct that prioritizes gamer engagement and spending over gamer safety."

The plaintiff. The complaint alleges that D.G., a minor, developed a gaming addiction that caused "severe emotional distress, diminished social interactions, loss of friends, poor hygiene," and withdrawal symptoms including "rage, anger, and physical outbursts," and that D.G. was diagnosed with depression, ADHD, and oppositional defiant disorder (ODD), requiring out-patient counseling, private tutoring, and a school accommodation plan.

Conspiracy theory. Like the other cases in this group, the complaint alleges that the defendants "conspired or acted in concert to addict a generation of young video game players," a theory the Judicial Panel on Multidistrict Litigation specifically discussed in declining to centralize the cases.
